SILL FOR llllliZEl'lAI WINDOW-FRAMES.

Specification of Letters Patent.

Patented June 28, 1921.

Original application filed July 1, 1919, Serial No. 307,945. Divided and this application filed February 12, 1920. Serial No. 358,112.

To all whom it may concern:

Be it known that I, IRVING H. ELLIOTT, a citizen of the United States, residing at New York, in the county of New York and 'State of New York, have invented a certain new and useful Improvement in Sills for Metal Window-Frames, of which the following is a specification.

The invention relates to a sill for metal window-frames of the type set forth in U. S. Letters Patent No. 1,237 ,295 to Harry E. Campbell, dated August 21, 1917, and is a dvision of my application Serial No. 307,945, filed July 1, 191$). The invention consists in the construction whereby any moisture accumulated on the sill is caused to drain outwardly, and is so prevented from flowing into -.the room or building over the inner edge of said sill In the accompanying drawing- Figure 1 is a front view of my sill, showand the rib 7, and also the broken away to show said rib. Fig. 2 1s a cross section on the line as, a; of Fig. 1.

Similar letters and numbers of reference indicate like parts.

The sill B is a' casting resting upon the masonry of the window opening. It has a. flat portion 1 united to an outwardly and 2 by a vertical portion 4. Near the outer edge of the flat portion 1 is a groove (3. The top surface of rib 7 formed between the groove 6, and the vertical portion 4 lies below the level of the Hat portion 1, so that any water accumulating on said flat portion 1 and entering the groove cape to the vertical and outwardly inclined portion of the sill. In this way, said 5111 is drained and water prevented from flowing1 into the building over the rear edge of Sai' flat surface.

6 will flow over said rib 7, and so es- The lower member of the lower sash which moves vertically in the hollow windowframe,the jambs of which are shown at C, has a vertically projecting plate 41 which, when said sash is closed, bears against the vertical face 4 of the sill.

and then turned downward, so that when said sash is closed said downturned portion enters groove 6 in the sill. Hitherto, where the lower sash has been constructed, as described, to cooperate with a rib on the sill received between plates like 41 and 42, said rib projects above the level of the flat portion 1 of the sill, and so forms a dam preventing the escape of water lodging on said flat portion. But by placing the rib below the level of the fiat surface 1 of the sill, it is obvious that this dam is eliminated, and that there is always free drainage of the water over the rib and so to the outer inclined sill surface.

I claim:

A metal window sill, comprising integrally an inner fiat portion having a longitudinal groove near its outer edge, a vertical portion outside of said groove, and an inclined portion outside of said vertical portion, the upper edge of said vertical portion being below the plane of said flat portion, in combination with a sash having its lower rail formed of an inner plate adapted to enter said groove and an outer plate united to said inner plate, bearing against the outer face of said vertical portion of said sill and extending below said groove when said sash is inclosed position. i

In testimony whereof I have afiixed my signature in presence of two witnesses.
